REL/5 CARTON WITH LOCKED HANDLE AND LID CONSTRUCTION One of the principal objects of this invention is to provide a carton having a handle member formed by upstanding portions of the top panels of the carton, together with structure for locking such upstanding portions in place.

Another object is to provide improved carton having six sides and to form a handle for the carton by structure which is a part of the top panels and which consists of handle elements arranged to be in confronting relationship, certain of the panels having tab extensions therefrom arranged to lock with the handle elements to maintain the top thereof in assembled relationship.

The improved carton according to the present invention is referred to generally by the reference numeral and is formed from a unitary cut and scored blank 15A seen in FIG. 2. Carton blank 15A 'is comprised of a plurality of hingedly connected side panels I6, l7, 18, 19, 21 and 22 foldable along score lines 23 therebetween. A glue flap 24 is foldably connected to end panel 16 along a score line 26, and glue flap 24 may be glued to panel 22 to define a carton sleeve. It may be noted that the outer sideof the blank 15A is shown in FIG. 2.

A bottom panel 27 is hingedly connected to side panel 18 at a score line 28, and bottom panel 27 is divided intobottom panel sections 29 and 31 foldable with respect to each other along a score line 32 coincident with the major diameter of the bottom panel 27.

A glue flap 33 is foldably connected to the side panel 22 opposite from side panel 18 along a score line 36. A glue patch 34 on the outside face of glue flap 33 is glued to the inside face of the bottom panel section 31. The bottom panel 27 is reinforced when thecarton according -to the invention is in the set up position as seen in FIG. l by a flap sector 37 hingedly connected to panel 16 along a score line 39. Flap sector 37 is glued to a flap sector 38 hingedly connected to panel 17 adjacent to panel 16 along a score line 41. Flap sector 38 has a glue patch 42 thereon on the opposite side of the blank 15A from that seen in FIG. 2, and the two flap sectors 37 and 38 are adapted to be glued together as seen in FIG. 7.

In the same fashion side panel 19 has a flap sector 43 hingedly connected thereto along a score line 46, flap sector 43 cooperating with a flap sector 44 hingedly connected to the adjacent panel 21 along a score line'47. Flap sector 44 has a glue patch 48 thereon for gluing of the flap sector 44 to the flap sector 43 in the same fashion as was described with respect to flap sectors 37 and 38 seen in FIG. 7.

Structure is provided for forming a top panel of the carton l5, and for providing a structure whereby the same can be transported. To this end panel 18 has aflap extension 49, and side panel 22 also has a flap extension 51, the two flap extensions 49 and 51 being foldable with respect to their panels 18 and 22 along respective score lines 52 and 53. Flap extension 49 includes a half cover portion 54, as does also flap extension 51 which has a half cover portion 56. Each of the half cover portions has a handle portion 57 foldable with respect thereto in a position of confronting relationship with respect to each other along respective score lines 58 and 59. Each of the handle portions 57 is provided with a handle tab 61 defined by a out line 62 and a score line 63. The two handle tabs 61 being positioned out of the plane defined by the confronting handle portion 57 as seen in FIGS. 5 and 10.

. Structure is provided for locking the confronting handle portions 57 together and for providing additional stiffness to the half cover portions 54 and 56. To this end, adjacent side panels 16 and 17 are provided jointly with a locking tab 64 foldable with respect to the panels 16 and 17 along a score line 67. Adjacent panels 19 and 21 are likewise provided with a locking tab 66 foldable with respect to the panels 19 and 21 along a score line 68. Each of the locking tabs 64 and 66 is provided with a gusset fold 69 and a fold line 71 dividing the tabs 64 and 66 into two portions adapted to be folded down along side the confronting handle portions 57 as seen in FIGS. 1 and 3. By reason of the gusset folds 69 and center fold 71, the locking tabs 64 and 66 can closely flank the confronting handle portions 57, the remaining portions of such tabs overlying the half cover portions 54 and 56.

Each of the locking tabs 64 and 66 is provided with an essentially diamond-shaped opening ,72 adapted to permit locking ears 73 on the confronting handle portions 57 to protrude therethrough when the-half cover portions 54 and 56 are positioned as seen in FIG. 1.

The improved carton according to the present invention can be shipped as a flat partly formed carton blank. In the steps of erecting the carton, the side panels form the same into a hexagon, the flap sectors 37, 38 and 43, 44 supporting the bottom panels 27 which folds to the position seen in FIG. 7 along the score lines 32 thereof, bottom panel sectors 29 and 31 resting against the aforementioned flap sectors. Thereafter the half cover portions 54 and 56 are folded into position along their respective score lines, the confronting handle portions 57 being folded together. Pressure is then exerted downward, so that the half cover portions 54 and 56 are no longer in the plane of the top of the carton. Locking tabs 64 and 66 are then folded about the confronting handle portions 57 so as to flank the same and overlie the half cover portions 54 and 56.
